FiiO A1 Compact Digital Desktop Power Amplifier (FiiO A-1) [HH00649]

FiiO A1

FiiO A1 Compact Digital Desktop Power Amplifier. A1 signals FiiO's outreach to the Hi-Fi amplifier world with this digital power amplifier. The FiiO A1 is an advanced compact desktop stereo amplifier designed to provide high fidelity amplification for playback on small bookshelf speakers or un-powered monitors. It combines both a preamp and power amp in the same chassis, able to take input directly from a line-level source.

High performance TI OPA2134 audio operational amplifier for preamp circuitry with low noise, low distortion and high conversion rate. Each of the two sound channels use a different carrier frequency (550KHz / 600KHz) to achieve high fidelity conversion and minimized mutual interference. The Differential input level of FiiO's A1 combined with adjustable negative feedback circuit ensures low noise, low interference and low distortion.
